  • Drug-eluting catheter and method of manufacturing the same
    Patent number: 9186439
    Abstract: Biocompatible nanoparticles 1 which entrap a bioactive substance and whose surface is positive-charge-modified are electrically adhered to a balloon portion 9 of a catheter main body 5 through a negatively charged resin layer 11, and thus a nanoparticle layer 12 is formed. After the catheter main body 5 is indwell in vivo, the nanoparticles 1 are gradually eluted from the nanoparticle layer 12 and are effectively delivered to cells.
    Type: Grant
    Filed: March 12, 2009
    Date of Patent: November 17, 2015
